What is the force that a 873 kg dragster attains when he accelerates at an average of 45 m/s2?

F = ma

F = (873)*(45)

F = 39,285 N

How much force do you exert if you push a 25 kg box at a rate of 3.5 m/s2?

F = ma

F = (25)*(3.5)

F= 87.5 N

What is the mass of a swimmer that accelerates towards the water at 10 m/s2 and hits the water with a force of 3200 N?

F= ma

m= F/a

m= 3200/ 10

m = 320 kg

What is the mass of a cat that accelerates at 1.0 m/s2 after a force of 100 Newtons has hit it?

F = ma

m = F/a

m = (100)/(1)

m = 100 kg

If a weather balloon has a mass of 5 kg and is released with a 98 N force upward, what is the acceleration of the balloon?

F= ma

a = F/m

a = (98)/ (5)

a = 19.6 m/s²

Open Ended

How big is the acceleration of a 2325 kg truck if the force exerted is 10000 N?

F = ma

a = F/m

a = (10,000) / (2325)

a = 4.30 m/s²
